CABLE SAW 'FOR- TREES.

Application led November 30, 1923,. Serial No. 677,633.

To all whom t may concern.'

Be it known that I, PETAR JOHN Lucien, a subject of the Kingdom of Serbs, Croats, and Slovenes, Yugoslavia, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Cable Saws for Trees, of which the following is a `speciiication.

This invention relates to improvements in means and devices for changing landscape profiles by levelling natural elevations, filling valleys, providing` drainage and like operations of an extensive scope, and others of lesser' magnitude, such as felling trees, even removing such portions of their stumps, as might interfere with agricultural pursuits, from below the surface of the soil and incidentally cutting the tree trunks into convenient lengths to suit the purpose for which they may be used.

The several aims and objects of the invention are to provide new and effective systems, methods and apparatus for effecting topographical changes, lumbering or deforestation and preparation of the'surface for agriculture and husbandry, for encampments or preliminary to the building of towns.

ln addition to these broad general purposes, many others of minor nature, but relatively important in themselves, will become manifest in the following specification in which illustrative embodiments are describe( and shown in the accompanying drawings, constituting a material part of this disclosure, and in whichz- Figure 1 is a general perspective view of` a simple embodiment of the invention, illustrating its application to tree cutting.

Referring to the drawings more in detail, Figure 1 presents graphically and generally the application of a simple form of the inc meral 21 and is here indicated diagrammati- I cally, rather than specifically, the embodiment being of very simple character.

This apparatus comprises a base 22 having raised side' elements 23 and 30 and a corresponding central element 25. Rotatably mounted in the yelements 23 and25 is a drum v26,provided with'rotative means as indicated by the handle 27. y

A similar drum 28 is mounted in the elements 30 and 25, having operating means 29 'and rearward of the drum 28 is another drum 24.*. i 4, y

At the vopposite iside, rearward of the` drum 26 are two drums 31 and 32, each, being provided with individual operating means, such means'kbeingy understood to be motor or hand driven as preferred.

. The tree V16 is provided `with a guyv rope 33 and the trunk 17 with a like rope 311,.l both ropes being secured to the upperr portion of the tree trunks and extended down to a rigid fastening means, as thev stump 20; the trees are` lconnected by a cable 35 tending to steadyA and measurably support the same. y ,l i

Attached. to the upper parts of the trees 16 and 17 yand also at points neartheir stumps, are harnesses including substantially vertical members 36 and 37 respectively and slidably mounted'on thesev elements are eyes 38 and 39jc'arrying pulley blocks L10 and Li1.' f

Said blocks are raised orI lowered by cables 42 and 43 passing over pulley block 44 and 45 lcarried `byvloops 146 and 47, .fixed to the 'trees at points as high as may beconvenient, the cable 42 being-engaged -on -the drum 2y and the corresponding cable 43 connected with the adjacent drum 3l.'

' Passing through the block 40 :is a cable .48 engaging the drum26 at its lower end and vvith a saw 50 at its opposite-end, -said savv being stressed by the cable 49 connected .to 'the drum 28. I e The saw' bla-de 50 is disposed substantially in a horizontal lplane and in' operative contact vvithvthe .tree 15, against which `it is drawn a rope 51, which may be passed over a guide pulley 52 attached to any convenient anchorage as the stump engagedon the drumy 24.

The operationof securing the harness of '-ropes, guys, sheaves or lpulley bloclrs and cables -is .easily performed, their disposition vbeing vdetermined by 'the .relative location of' the trees, which 'obviously vary inv nearly every occasion. v a The cables 42 and 43 aie controlled iny dependen'tly by the drums 82 and 3l 'so the height of the saw blade 50 may be adjusted as required and the thrust of the saw 'largely -taken "by the .cable 51 controlled by the drum 24, 4theseseveral drums'requiring little or 'no movement When originally ady usted.

Obviously the drums 26 and 28', whichV actuate the cables 48 and 49 Aand have operative engageinen't With the saw blade 50,

Vrequire constan'tffor-ivard and reverse inove-` inent in order to 1properly reciprocate the saw and the rotary movement 'of the drums must be synchronized in order to maintain l Figure i3 ofthe drawings indicates the v'manner `of cutting the ylogsof fallen trees in shorter lengths, sucli'logbeing desigy nated bythe numeral'60, 'adjacent its stump l6l, there l.being two other stumps 62 and 63 in its vicinity. y

Attached to :the 'last named stumps is a v.stout `cable 64, they same being under tension "und 'ha-ving slida'ble upon it an eye 65 carryiiig a -two Wheeled sheave block l66 in whichis threadedcables 67 and 68.

The 4`outer ,ends of ythese cables are lconnected With ,drums (not shown) by which Vthey are moved reciprocally and their inner, adjacent ends are engaged y,with the passed around .ends `of a 'flexible cutter 168 theflog aslshovvn. i

' he -tru iik70"is shown as partially separated-.from its stump 7l, inl Figure 4 by a ,s'a\v,`lreif o'i transverse cut 172, vparallel With the base and extending to a point slightly shown, the other end of the cable 51 being properly `levelled,

past 'the center of the tree, said cut being made in the side of the tree `from ythe direc-4 Another phase of the invention `is clearlyy illustrated lin .Figures 6 and 7 in `Which 'the surface-of the land K4is `designated bythe numeral 80, the `field or ground being newly cleared-buthaving a plurality of stumps 8l,

distributed with the usual and natural Virregularity, such stumps and roots obviously interfering with the necessary preparation and'tillage 'of the soil.

. `rIny order fto cut Volf fthe stumps at such l l distance Ebelow 'the Tlevel of the ground-as Sto avoid entanglement or prevent obstacles toy agricultural implements, .as plovvs, subsoilers and the like, the ground .is laid .off into fields -oi plots, lrectangular vor ctherivise and l having curved' corners kas shox/vnr in Figure 6.

A trench 82 is dug to encircle the `field, the ends of the ftrench at one point being entered into a pit orshallovv;k excavation 288 in Which `is placed a sturdy apparatus of the `kind -indicated at 21y 'in fFigure 'l but 'comprised of fewer parts.

, In lthe lpresent case ra base v84 ispr-ovidcd With side velements 85 andv 86 in which are vat intervals, it will act to'slice the turf fromthe subsoil, cutting and rendingany objects fin jits Way as ithe stumps and roots shown,v

so that they can befeasily removed. n

A still further adapt-ation Iof fthe sawing process is illustrated in 4fFigure 8 `which 4shoivstivo liills'ornatural'elevations 1100 and "101 having Fbetiveeii `them a lvalley voi'ldepres- `tions .'it is advisable to provide a pipe F103'y of adequate size, which after 'having'been may 'be enveloped in cement as at 104.k f l ,f j

Cuts are thenmade lin the hills 100 vand 101 as indicatedby the broken lines "105 and 106, completely separatingthe upper rportieri iccy of the hills, these cuts being made by devices as previously generally indicated and which will later be more specifically treated.

These cuts are directed angularly downward towards the valley and at such in clination as to cause the hill tops to slide by gravity into the valley, the area of which has been tal-ren into careful consideration in detern'iining the portion of the hill which will be required to fill the same.

Such Works of magnitude are of course accomplished under the supervision of a competent civil engineer and in fact use has been made of this disclosure for such 3 purposes.

The cutters used throughout the several applications herein shown and described are illustrated in detail in Figures 9 and 10 but Will vary in size and proportions in accordance with the Work expected to be performed by them.

In general the cable 110 represents those designated heretofore by the numerals 48, 4S). (3T, 68, 89, 90, and thev cutter 111 as being the equivalent of those designated by the numerals 50, 68 and 93.

The detail Figure 9 shows the cable 110 to be engaged to a head 112 by means of a removable pin 113 held in the outer forked end of the head, in the solid end of Which is rigidly xed one end of a flexible rod 11st` the other end of the rod being engaged in like manner to the complementary cable.

Strung on the rod 114 are a plurality of cutters 115 arranged in juxtaposition and independently rotatable. Each cutter consists of a hub portion 116 from Which radiate a generally star shaped ligure composed of a plurality of angularly or pyra1nidal shaped elements 117 converging to sharp points 118, each element 117 having sharp edges presenting cutting facets, understood to be both tough and hard, and capable by longitudinal movement of the rod 11e, imparted by the cables, to cut through twood, soil or rock formation in a highly effective manner.

`Although the foregoing presents several embodiments ofthe invention, and illustrates their practical application, it will be readily understood that other modifications may be made from the disclosure and Which are all Within the scope of the appended claims, such minor changes not involving inventive genius but rat-her the skill of an artizan experienced in and familiar with the lines of Work herein indicated.

Having thus described `my invention, What I claim as nevvand desireI to secure by 1. In a cutting apparatus, harnesses engageableivith supports and each including a vertical guide member secured at opposite ends to its support, a pulley block movable longitudinally of each guide member, flexible elements connected to said pulley blocks for raising and lowering the same along said guide members, other flexible elements passing around said pulley blocks, a iiexible cutter connecting adj acent'ends of said other flexible elements and capable of engagement with an object to be cut, and means for ac-` tuating said other flexible .elements to reciprocate said cutter.

2. In a cutting apparatus, harnesses engageable with supports and each including a vertical guide member' secured at opposite ends to its support, a pulley block movable longitudinally of each guide member, flexible elements connected to said pulley blocks for raising and lowering the same along said guide members, other flexible elements passing around said pulley blocks, a flexible cutter connecting adjacent ends of said other flexible element-s and capable of engagement with an object to be cut, and drums to which the various flexible elements are connected for actuating the flexible elements joined to said pulley blocks and for reciprocating said cutter.

In testimony whereof I have affixed my signature.
